Hexagon: list available CPUs with -cpu help

Browse Source 
Currently, qemu-hexagon only models the v67 cpu. Nonetheless if we try
to get this information with `-cpu help`, qemu just exists with an error
code and no output. Let's correct that.

The code is basically a copy from target/alpha/cpu.h, but we strip the
"-hexagon-cpu" suffix before printing. This is to avoid confusing
situations like the following:

    $ qemu-hexagon -cpu help

    Available CPUs:
      v67-hexagon-cpu

    $ qemu-hexagon -cpu v67-hexagon-cpu ./prog

    qemu-hexagon: unable to find CPU model 'v67-hexagon-cpu'
